摘  要：
利用多期遥感资料,分析了新疆玛纳斯河流域1972—2013年的冰川变化,并对其原因进行了分析。结果表明:1972—2013年冰川共退缩了159.02 km2(变化率为-24.61%),海拔3 800~4 200 m之间退缩最为强烈,冰川末端海拔升高明显(41 a间海拔3 200~3 300 m之间的冰川消失)。冰川变化存在一定的区域差异性,玛纳斯河主源冰川退缩速度最快,左岸次之,右岸退缩速度最慢。从朝向上看,各个朝向的冰川均处于退缩状态,偏东向的冰川退缩面积明显大于其他方向。近40 a,流域冰川总储量减少了59.09~85.94 km~3。与中国天山其他地区冰川相比,该流域的冰川退速率较高,气温升高是该区域冰川退缩的主要原因。

摘  要：
The variation of glaciers in the Manas River Basin,Xinjiang,China was studied based on the multiphase remote sensing images. The results revealed that,during the period of 1972- 2013,the total glacier area in the study area was reduced by 159. 02 km2,the reduction rate was as high as 24. 61%,the most remarkable shrinkage of glaciers occurred in an elevation range of 3 800- 4 200 m a. s. l.,the terminal altitude of the glaciers ascended obviously,and the glaciers in an altitude range of 3 200- 3 300 m a. s. l. disappeared in recent 41 years. Glacier variation was quite different from different regions,the shrinkage rate of the main-source glaciers in the Mannas River Basin was the highest,than that on the left bank,and that on the right bank was the lowest. Glacier shrinkage occurred at all the slope aspects in the Manas River Basin,especially on the east slope. It was found that the glacier volume in the study area was reduced by 59. 09- 85. 94 km3 in recent 41 years. Shrinkage rate of glaciers in the Manas River Basin was higher than that in other regions of the Tianshan Mountains. Air temperature increase was the main cause resulting in the shrinkage of glaciers in the study area.
